It also provides high precision, low dropout voltage, current limit, temperature protection and short-circuit protection.

Application Field

The RT9011-GGGQWC is used in many applications such as industrial and consumer electronics, automotive, communications, computers and peripherals, utility meters, instrumentation and medical instrumentation. It can be used as a power supply for a wide range of devices such as LCDs, motors, Solenoid drivers, LEDs, LEDs and other power-sensitive equipment. It is also ideal for powering low power circuits, as well as regulating power supplies.

Working Principle

The RT9011-GGGQWC is a 3-terminal adjustable regulator, suitable for a wide range of power supply applications. It provides a constant regulated output voltage with a wide input range, by using an external resistor divider. The output voltage can be selected by adjusting the value of the resistor divider. An internal reference voltage of 0.8V ensures tight output regulation and overload protection. The device also includes an overload protection circuit to protect from excess current draw.

The device works by sensing the input voltage and outputting a proportional voltage to the regulator. This causes a current to flow through the output terminal and the load, thus maintaining a constant output voltage. The adjust input allows for the adjustment of the output voltage. The current limit is adjustable via a resistor connected to the control pin. The current limit is set to a maximum of 2A.

The RT9011-GGGGQWC comes with a thermal shutdown feature, which protects the device in the event of an overload or over-temperature condition. The device also has an anti-phase shift circuit which prevents the output voltage from dropping when the input voltage is reduced.

Conclusion

The RT9011-GGGQWC is a linear voltage regulator designed to provide a wide range of input voltages and precision output voltage control, with minimal external components. It features current limit, temperature protection, and short-circuit protection, ideal for powering low power circuits and regulating power supplies.
